While negotiations between the Calle Serna brothers and U.S. authorities are apparently in the works, there have been no confirmations of surrender.

On InSight Crime’s website, analyst Jeremy McDermott wrote, “Two high-level law enforcement sources, as well as a third source very close to the case, told InSight Crime that Calle Serna was not in US custody.”

Rumors of the Calle Serna brothers’ surrender have circulated through media for months.
